Oh man! This gave me a great idea for a video game ! Wouldn't be a big seller, though, not enough people couild do it, BUT.......
You know those car race games like Ferarri challenge, with the curved screen that sort of gives a surround appearance? Well, what if the screen was an orchestra playing. And in the setup, after you've dumped a million quarters into the machine, you could pick your piano, and the orchestra conductor, and the concerto - see where this is going?
And the "game" would be a piano keyboard instead of a steerring wheel or gun, and after the concerto intro youwould have to come in on time playing the concerto - not to worry, the music would be displayed in front of you, moving along as you played with the orchestra. And at the end you'd get a score.
Whaddya think? Would I make millions?
